Drywall joint fixture and method

ABSTRACT

A drywall-joint fixture has a drywall-joint cover ( 1, 33, 37, 42 ) that can be attached to a drywall arch, wall flat or other drywall structure after a first sheet ( 3 ) and a second sheet ( 4 ) of drywall of the drywall joint are positioned on wall framework ( 5, 35, 39 ) of a building. A paper face ( 49 ) that is resistant to sanding is positioned on the drywall-joint cover. The drywall-joint cover includes a first side ( 6 ), a second side ( 7 ) and an attachment flange ( 8 ). The attachment flange is extended orthogonally from an inside surface of either the first side or the second side and is longer than a side opposite from which it is extended for receiving fastener shanks ( 12 ) that are stuck through sheets and into a wall framework. A selection of shapes are provided for differing wall structures. A method includes using the attachment flange to maintain the drywall-joint cover in place.

BACKGROUND OF THE INVENTION

This invention relates to structure of drywall joints for corner beads,arches, edges, flats and other drywall applications after the drywallhas been positioned.

Drywall cornering, beads and joints are a common feature of constructionof private and many commercial dwellings and business structures.Numerous devices and methods for joining drywall at corners, archeswindows and flats are known, but continue to be devised because nonehave proved sufficiently adequate to satisfy needs of this feature ofconstruction. Included have been freehand plastering and many differingrigid corner beads, paste-on beads, tack-on beads and combinationsthereof.

None, however, have post-positioning corner beads and joints for alldrywall applications in a manner taught by this invention.

SUMMARY OF THE INVENTION

Objects of patentable novelty and utility taught by this invention areto provide a drywall-joint fixture and method which can decrease costsfor installation of all forms of drywall construction substantially.

This invention accomplishes these and other objectives with adrywall-joint fixture and method having a drywall-joint cover that canbe attached to a drywall joint, arch, wall flat or other drywallstructure after drywall is positioned on wall framework of a buildingand before the drywall and the drywall-joint cover are surfaced withpaint or other wall cover. The drywall-joint cover has a surfacecovering for each of at least two drywall surfaces to be covered by asingle drywall-joint cover. Intermediate a front surface covering and aside surface covering of the drywall-joint cover is an attachment flangefor being extended from an inside surface of the drywall-joint cover andinserted between an end edge of a first drywall and a joint edge of asecond drywall. Fastener shanks are affixed through a side drywall andinto the wall framework. The attachment flange is inserted between theend edge of the first drywall and the joint edge of the second drywall.Then a side-surface covering is positioned on and fastened to theside-positioned drywall and a front-surface covering is positioned onand fastened to the second drywall.
